| Subject: kernel: kcsan: kcsan_test: build without structleak plugin |
| Date: Mon, 28 Nov 2022 11:43:58 +0100 |
| |
| Building kcsan_test with structleak plugin enabled makes the stack frame |
| size to grow. |
| |
| kernel/kcsan/kcsan_test.c:704:1: error: the frame size of 3296 bytes is larger than 2048 bytes [-Werror=frame-larger-than=] |
| |
| Turn off the structleak plugin checks for kcsan_test. |
